hi all,
I am getting multiple driver error in my vhdl program.So pls help me.
My program is to connect two rams to processor put data into rams
through processor then disconnect them from processor.Then do the
operation with data present in rams and processor should read the
result.is there otherway to do this project.
I am using xilinx 12.2 tool.
I am attaching the code getting errors so pls help me..
errors are:
Error:XST:528:Multi-source in Unit<procint> on signal
<Mcount_adresss_cy<0>>; this signal is connected to multiple drivers.

This error means: you are driving (at least) this signal from more than
(at least) one process. Or you are driving this signal from a process
and a concurrent statement...
The problem in your code is addresss, its driven from 2 processes.
But there are al lot of more problems to come!!!
Lots of them are reported in the warnings. This are at least highest
warning level, maybe this should be an error:

WARNING:Xst:737 - Found 1-bit latch for signal <s1>. Latches may be generated from incomplete case or if statements. We do not recommend the use of latches in FPGA/CPLD designs, as they may lead to timing problems.
WARNING:Xst:737 - Found 1-bit latch for signal <s2>. Latches may be generated from incomplete case or if statements. We do not recommend the use of latches in FPGA/CPLD designs, as they may lead to timing problems.
WARNING:Xst:737 - Found 1-bit latch for signal <done>. Latches may be generated from incomplete case or if statements. We do not recommend the use of latches in FPGA/CPLD designs, as they may lead to timing problems.

This incomplete sensitivity list does not cause your problems!
Its just another problem.
> Please suggest me what to do for that multiple error.
Don't assign values from more than 1 process to a signal. I already said
tis:
>>> This error means: you are driving (at least) this signal from more>>> than (at least) one process.>>> The problem in your code is addresss, its driven from 2 processes.
